Component License Notes
Original Shor / Beauregard implementation (Shor.py, Aprox_Shor.py, notebooks on english / spanish) Apache-2.0 Copyright 2024 Alejandro Mata Ali — see LICENSE
aprox_phase_estimation_wqft.py (on english / spanish) EUPL-1.2 Derived from QQuantLib / NEASQC FinancialApplications; original authors Gonzalo Ferro Costas & Alberto Manzano Herrero; QFT/approx work by Alejandro Mata Ali — see LICENSES/EUPL-1.2.txt and NOTICE

Full third-party attribution is in NOTICE. The same LICENSE, NOTICE, README.md, and LICENSES/EUPL-1.2.txt files are also present on the english and spanish branches so a code checkout carries the licensing materials.
